A woman comes home late in the night and goes quietly in the bedroom.
To her surprise, she sees male and female feet peeking out from under the blanket.
Shocked and raging, she gets her baseball bat and beats and beats until all movement stops.
After that she goes into the living room and sees her husband laying on the sofa. He turns to her half asleep: “Oh, you’re home, darling. I’m afraid we have to sleep here tonight, my parents came for a surprise visit.”
